The stakes are high for candidates Tuesday in Illinois. Races are expected to be tight from the presidential nominations right down to state legislative contests. Even if you've moved or haven't yet registered to vote, there's still time.
Illinois politicians have themselves voted in recent years, to make it easier for Illinois residents to vote them in (or out) of office.
This is the first time voters statewide can take advantage of being able to register on election day.
But a word of caution from the Illinois State Board of Elections' attorney, Ken Menzel: Check with your local elections authorities first to find out precisely where to do it.
"They can't just pull out of their subdivision and pull in at the first place they see flags out at the street ... unless that happens to be the polling place that serves their address," he says."If you're going to wait to register at one of those you have to go to the specific one that serves your address. And there's only one of those for each voter."
It's also the first time that Illinois is permitting 17-year-olds to vote, as long as they will have their 18th birthday before the general election in November.
Polls are open until 7 p.m.
